MANUFACTURE OF PAPER BARRELS.

SPECIFICATION forming part of Letters Patent No. 410,726, datedSeptember 10, 1889.

Application filed May 9, 1888. Serial No. 273,270. (No model.)

To all whom it may concern:

Be it known that I, AUGUST BRAB, a subjectof the Kingof Prussia, GermanEmperor, residing at the city of Ehrenfeld, near Oo logne, in theKingdom of Prussia, German Empire, have invented certain new and usefulImprovements in the Manufacture of Paper Barrels, of which the followingis a speciing ropes on them, as will be fully described hereinafter, andpointed out in the claims.

In the accompanying drawings, Figure 1 is an end elevation of the core011 which the barrel is made. Fig. 2 is an end view of the blank,showing the same rolled up as it is when forming part of the barrel.Fig. 3 is a plan view of one of the paper blanks for male ing the shellof the barrel, said blank being shown extended. Fig. & is a side view ofthe completed barrel. Fig. 5 is an end view of the same. Fig. 6 is avertical longitudinal section of the barrel and the apparatus forrotating it. Fig. 7 is a top view of the barrel and thedevice forpressing the layers of the same. Fig. 8 is a side view, and Fig. 9 afront elevation, of the apparatus shown in Fig. 7. Fig. 10 is a detailenlarged vertical transverse sectional view of the barrel, showing themanner in which the wires are fastened in the bung-hole. Fig. 11 is adetail cross-sectional view of the rubber stopper. Fig. 12 is a topview.

Similar letters of reference indicate corresponding parts.

The barrel is made on a core composed of a center piece 1 and theexterior pieces 2, 2, 3, 3, 3 and 3, Fig. 1, and is tapered from themiddle toward its ends. A shaft is passed longitudinally through thehole in the center of the central piece 1 of the core, which shaft has acrank-handle thatis mounted in suitable supports for turning it. Thecore is provided near each end with an annular groove h. Into the same apaper ring h is placed,which is wedge-shaped in cross-section, as shownin Fig. 6.

The walls of the barrel are composed of a series of paper blanks B,provided in the longitudinal edges with triangular or tapered notches B,so that the blank has the appearance of a number of barrel-staves placedside by side. The first blank B is placed upon the core and its endssecured to the beveled outer edges of the rings h by means of cement orsome other suitable adhesive substance. In this manner a number ofsheets of paper or blanks are secured on the core, each sheet beingcemented or secured by adhesive material to the preceding sheet or blankand all said blanks extending to the outer edges of the rings h. Thesheets or blanks are placed in such a manner that their joints are notover each other, but alternately the solid portion of one blank coversthe joints of the adjacent blanks. The core and sheets on the same arethem placed between two standards, on which the shaft passed through thecore can be rotated by means of its crank i, Fig. 9.

The shaft carries a ratchet-wheel 5, with which a pawl 6 engages.

On the drum 7 two wire ropes 15 are secured and wound on the drum fromthe center toward the rims. The drum is provided at each end with abrake-band 12, connected with a lever 8, carrying an adjustable weight 9to admit of giving any desired resistance. The ends of the ropes aresecured to the core at the bung-hole of the barrel in the followingmanner: The ends \V of the wires are passed through the bung-hole andtheir ends bent over, and, if desired, may be bent to form a knot orhead. A tapering rubber plug W is then forced into the bung-hole for thepurpose of keeping the ends of the wires in place. A sliding rod WW ispassed through the tapering plug and is provided at the outer end withan eye W and at its inner end with a transverse plate W By pulling thesaid rod outward the plug can be removed from the bung-hole and thewires released. By turning the core or barrel by means of the crank theropes are gradually unwound from the drum 7 and wound on the barrel orcore from the center toward the rim. As the ropes are wound round verytightly, they exert a pressure and press the several layers togethervery firmly, and then the ropes are unwound and the completing of thebarrel can be proceeded with. The core is then removed, as the shellformed has sufficient strength and thickness to act as the core for thefollowing layers.

The heads of the barrel consist of two strong paper disks 0 and cl, ofwhich the disks 0 fit precisely within the rings h. The diameter of theouter disks d is such that their rims are flush with the outer surfaceof the layers d. Then more paper blanks or sheets are secured ontheshell, said outer blanks forming the thickness f ot the barrel andextending some distance beyond the outer disks dv of the heads.

In making very strong and heavy barrels a thick paste of wood or paperpulp is applied between the outer and inner layers of the shell.

Strong paper rings 1' are placed in the ends of the shell and againstthe outer disk (Z of the heads, and are cemented or secured by any otheradhesive material to said heads and the projecting part of the shell f,the said shell being turned off flush with the outer faces of saidrings. \Vooden blocks f are placed on the heads within the rings 0", andthen the ropes are again wound onthe barrel for the purpose of pressingthe outer layers firmly together. l/Vhen that part of the barrelconsisting of the layers a is completed and the core has been removed,the bung-hole m is cut flaring from the exterior toward the interior,this being done before the heads are inserted. Strongiron hoops or bandsare then applied on the barrel, and the ends are secured by means ofscrew-clamps. The barrels are then made water-proof. Then the barrelsare painted on the outside withlinseed-oil,

the outside.

and are then baked in an oven at 120 to 140 Reaumur until they are ashard as wood on The hoops m are then driven on, and the ends may besecured by means of angle-irons. Beer-barrels are pitched in the usualmanner.

Barrels for other liquids are provided with a suitable coating, thenature of which must correspond to the nature of the liquid for whichthe barrel is to be used, and which -coating must not affect the color,smell, or flavor of the contents.

Having thus described my invention, I claim as new and desire tosecureby Letters Patent 1. The method of making paper barrels,consisting in pasting a series of sheets of paper one upon the other,and then winding ropes under pressure around said pasted sheets for thepurpose of pressing them together, substantially as herein shown anddescribed.

2. The method of making paper barrels, consisting in pasting a number ofsheets upon each other on a core, then removing the core, then insertingheads in the ends of the shell thus formed, and then pasting anotherseries of sheets of paper upon the first series and over the edges ofthe heads, substantially as herein shown and described.

3. The method of making paper barrels, consisting in placing rings onthe ends of a barrel-shaped core, then pasting a number of paper sheetsone upon the other around said core, then removing the core, thenplacing heads in the ends 01": the shell thus formed and against theabove-mentioned rings, and then pasting more sheets on said shell andover the edges of the heads, substantially as shown and described. I

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

AUGUST BRAL.
